TRUCK.

SPECIFICATION forming part of Letters Patent No. 637,044, dated November 14, 1899. Application filed February 27,1899. Serial No. 707,0A4. (No model.)

To aZZ whom it may concern:

Be it known that I,'GEORGE W. STRAIGHT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Truck, of which the following is a specification. i

This invention relates to trucks of the general type comprising longitudinal frame members secured together at a desired fixed dis tance from each other and truck-wheels revolubly mounted between said longitudinal frame members, and particularly designed and adapted for use in dry kilns for lumber, brick, and the like.

A primary object of my invention is to pro- 'vide a truck of this type which will embody the features of great strength and rigidity with simplicity of construction and relative cheapness of manufacture.

To this end the invention consists of the Va rious features and combinations of features hereinafter shown and described.

In the accompanying drawings a truck of my invention is fully illustrated.

Figure 1 is a side view of a truck of my in- Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged transverse vertical sectional view through the axle of one of the truck wheels, and Fig. 4 is an enlarged plan section on the line 4. 4: of Fig. 2.

Referring now to the drawings, A designates the longitudinal frame members of my truck, consisting, preferably, of light steel The truck-wheels A are preferably pro-' vided with antifriction-bearings and are mounted upon axles A secured against rotationin the longitudinal frame members A. In the preferable construction shown the axles A are provided with reduced ends a which are made slightly tapering,beingsmall-- est at their outer ends. The reduced taper ends a are forced into alined holes formed in the longitudinal frame members A, thus securing said axles against rotation in the desired manner. a

I claim I A truck comprising longitudinal frame members, consisting of channel-bars disposed with their plane faces toward each other, transverse frame members,-consisting of sections of channel-bars, the longitudinalframe members being riveted, or otherwise rigidly secured to the flanges of said transverse frame members and the extreme transverse frame members being disposed with their plane faces flush with the ends of the longi* tudinal frame members, and truck-wheels revolubly mounted on axles between said longitudinal frame members, the ends of said axles being tapered and being secured by frictional engagementin holes formed in the longitudinal frame members, substantially as described.

In testimony that I claim the foregoing as my invent-ion I have hereunto set my hand this 25th day of February, 1899.
